Times Online (U.K.) reports that having sex -- or at least ejaculating -- every day may help improve men's sperm quality. Yes, yes, most would-be parents know that couples who are trying to have a baby are often told not to let the guy ejaculate too often in order to protect his sperm count. And it's true that if you let the boys out every day, you're going to have, on average, fewer boys to let out (you've got to give them a little time to build up). But researchers from Australia are now suggesting that in cases where the guy's got fertility problems to begin with -- as defined by having sperm with DNA damage -- daily ejaculation is a good thing.
The pilot study only looked at 42 men whose sperm showed "significant" DNA damage -- but when those men were encouraged to ejaculate daily, their sperm's DNA damage was reduced by 12 percent. (The hypothesis is that the longer the sperm spends sitting around, the more damage it can suffer from exposure to free radicals.) The bottom line? If a couple's just started to try for a baby (i.e., they don't yet have a history of failed attempts), it could be useful to have sex every two or three days. But if a guy has a decent sperm count and high DNA damage, it could behoove him to empty his reservoir daily.
